Thank you guys, in the end I used the Univ. of Iowa samples.
Interestingly the new Nord samples cite this site
http://sso.mattiaswestlund.net/ which in turn cites:
"SOURCES
SSO was created from the following free/CC-licensed/public domain instrument samples: The University of Iowa MIS, MSLP, Philharmonia samples, OLPC project, The Complete K2000, ldk1609 violin, stamperadam Kelon Xylophone, Corsica_S Cello Pizzicato, davidjwoll cymbal rolls, Satoration Castanets, Thores Triangle, Mystified timpani, Eddie's English Horn and a variety of classic soundfonts by Campbell Barton, Nando Florestan and Ethan Winer."
So it seems that the oboe sample could be the same one from Univ Iowa. It is a nice sample, although I had to re-tune some notes, so there was no beating when playing on top of strings or piano.
